Interface MergeFunction

Functional Interface:
This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.
@FunctionalInterface public interface MergeFunction
Describes how to create the merged element for one ElementGroup.

Contract:

  • MUST call aliases.register(newId, oldIds) with the chosen new element id and the ids of all group members.
